Error in the range of the encoder.

What does 162 mean?

The traversing range of the absolute encoder has been exceeded. This means the physical travel of the drive has gone beyond the measurement capabilities of the installed encoder.

• Physical travel of the mechanical system has exceeded the maximum measurement range of the installed absolute encoder (e.g., single-turn limits, multi-turn beyond specified turns).
• Incorrect encoder scaling factor (e.g., Parameter C0301 for pulses per revolution, C0302 for gear ratio) causing misinterpretation of the actual physical position.
• Homing procedure established an incorrect zero point, leading to a calculated position outside the encoder's valid range during normal operation.
• Encoder damage or internal fault causing it to report values outside its specified operational range.
• System mechanics have physically moved beyond the intended safe travel, often due to an unrelated control error or collision.

Click steps to track your progress.

1. 1

   1. Verify the specified absolute encoder range (e.g., number of turns for multi-turn) and compare it against the actual mechanical travel of the axis.

2. 2

   2. Review and correct the encoder scaling parameters (e.g., C0301, C0302) to ensure accurate position calculation.

3. 3

   3. Re-perform the homing sequence to establish a correct zero position within the encoder's valid operating range.

4. 4

   4. Monitor the actual encoder raw counts (if available in diagnostics, e.g., P5-07) and physical position to pinpoint where the range is exceeded.

5. 5

   5. Check the encoder coupling for slippage or damage that could lead to misreporting of actual position relative to the motor shaft.
